Hi!
The IUD check will be important. They can use the ultrasound to image the IUD and make sure it is in the proper location. It IS possible to get pregnant with an IUD in place, so it never hurts to take a test. With the Mirena IUD it is extremely common to have irregular spotting for up to 3 months after insertion. I warn all of my patients that they can expect this. Also, it does not keep you from cycling, so most women have their normal PMS symptoms even if they don't get their periods.
If you can hang in there for awhile, most women really like the Mirena. It can be a real nuissance in the first few weeks though.
I hope this is useful!

no dont worry i felt the same way when i had mine put in 2/09 i totaly thought i was prego and when i went for my 6 week checkup took a prego test it was negative. and i started my cycle the next day.
On the other hand to be safe you should probaly sced a prego test. you know your body better then anyone else would. and if you r prego which is still possible even with an iud, you would need to get it removed asap for the babys safety.
GOOD LUCK
